Port Pirie Regional Council collaborated with Tonkin to develop a quarterly unsealed road inspection program and program grading to suit site conditions based on the road surface performance and impacts of traffic and weather. This solution includes integrated applications that provide the council with a workflow to remain proactive with grading operations, with benefits including safer roads, more efficient planning, a higher level of service to rate payers and potential cost savings.
With approximately 625 km of unsealed, regional roads to maintain, limited resources and budget constraints, the Port Pirie Regional Council needed an integrated spatial solution to improve patrol grading management. In a collaborative workshop, Port Pirie Regional Council and Tonkin identified the opportunity to develop a quarterly unsealed road inspection program separate to the standard road asset condition rating, undertaken every four years. These quarterly inspections have enabled the council to better plan grading works to suit site conditions, road surface performance and traffic and weather impacts.
The solution consisted of three GIS components, which utilised the council’s existing ArcGIS Online environment including:
An initial unsealed road inspection tool using Arc Collector/Field Maps - Field staff have undertaken inspections at the end of the preceding quarter every three months using this mobile application.
A condition review tool including an ArcGIS Online interactive web map with dashboard elements – The supervisor has undertaken a desktop review of inspection data to finalise the grading program and grade type, using the mapping and graphical elements of the review tool to take into consideration the priority and budget. Each quarter the grading program has been updated, finalised, and mapped on the grading program application ready for the grader operators.
A grading program tool also set up in Arc Collector/Field Maps - Grader operators have undertaken grading as per mapped program on this application. The required information has been filled in prior to grading and confirmed upon the completion of each segment after the road has been graded.
Seamless integration between these three processes provides Council with a workflow that supports proactive management of grading operations. Since adopting the quarterly inspection workflow, Port Pirie Regional Council has reported a range of benefits including:
More efficient planning of patrol grading
Better transparency of grading operations
A higher level of service to rate payers
This spatial solution has enabled Port Pirie Regional Council to move from reactive to proactive patrol grading, improving road safety and providing operational efficiencies for the council. The set up of the applications have also enabled the council to implement a repeatable and automatable process using GIS.
Future plans for the application are to provide a publicly available GIS viewer component, automate the integration of collected data with council's asset management system, and replicate the solution for other asset types and maintenance activities.
